Um, TPMs for sure provide meaningful security. Maybe their use is implemented poorly a lot of the time, AND they can be abused to hold control over hardware you've purchased, but low level exploits are for sure a thing and TPMs and other dedicated hardware security modules (for enterprise) most definitely serve a purpose.

They're a response to the ever evolving advancement of cyber exploits. Don't knock them on principle, take affront to when they're used poorly.
